WASHINGTON (AP) — Authorities have identified the man arrested in connection with a series of explosive devices mailed out to prominent democrats and critics of Donald Trump.

According to court and other public records, Cesar Alteri Sayoc Jr., 56, has a lengthy criminal and court record in Florida. He has been convicted on theft, stolen property and traffic charges and in 2002 on a threat to “throw, place, project or discharge any destructive device.”

Sayoc is in custody in Florida in the mail bombs sent to prominent Democrats. He was born in New York.

Sayoc was sentenced in August 2002 for threatening to throw a bomb in a conversation with a Florida utility representative, according to Ronald Lowy, a Miami attorney who represented him. Dade County court records showed Sayoc served a year’s probation after a judge signed a discharge certificate in November 2002.

Lowy told The Associated Press that Sayoc “made a verbal threat when he was frustrated at a lack of service.” Lowy said Sayoc showed no ability at the time to back up his threat with bomb-making expertise.

The lawyer said Sayoc was a bodybuilder then, and displayed no political leanings except for plastering a vehicle he owned with Native American signs.

Court records also show that Sayoc was convicted in the 1990s in Broward County on grand theft and stolen property charges and in 2004 on a felony charge of fraudulent refunds and misdemeanor of tampering with physical evidence.
